KraussMaffei, Germany, has supplied a line for the production of large-diameter PE-HD pipe (OD 400mm to 1,200mm) to Emirates Preinsulated Pipes Industries (EPPI), Abu Dhabi, United Arab Emirates. The line will be used mainly for the production of PU-insulated pipe used to transport cooling liquid for air conditioning systems in tower blocks. The extrusion line features a KraussMaffei Berstorff KME 125-36 B/R single-screw extruder with KM-RKW 36 and KM-RKW 38

pipeheads. Both pipeheads can be moved sideways out of the line on tracks. PES Productive and Industrial Co, Tehran, Iran has also started operating a KraussMaffei Berstorff line to produce large-diameter pipe. This line is headed by a KME 150-36 B/R extruder and a KM-RKW 39 pipehead. The line achieves an output of 1,700kg/h, producing PE-HD pipe with outer diameters up to 1,600mm. KraussMaffei Berstorff supplies complete turnkey solutions to produce large-diameter pipe, which are tailored to the specific requirements of individual users. RKW pipeheads are capable of producing pipe with diameters up to 2,000mm and wall thicknesses up to 100mm. The company’s 36 L/D single-screw extruder is capable of an output up to 1,700kg/h. The 36 L/D screw concept provides high output and a gentle, high-performance plasticising process. The longer processing unit delivers a thermally homogenous melt with fillers and pigment perfectly mixed in.
